Are you going to do your homework this evening or will you help your mother do the housework?

Possibly a better wording of the "rule" you quoted at the beginning of your question would be:
- In the question form we usually use a form of the auxiliary verb "do".

An example of its application is:

- (Declarative statement) He usually eats cereal for breakfast.

- (Corresponding question) Does he usually eat cereal for breakfast? {Here, "does" is the form of the auxiliary verb "do" that is being used.}

Note that we usually identify a verb by using its infinitive form. Some people emphasize that they are using the infinitive form by adding the word "to" before it; they think of "to" as part of the infinitive, sometimes calling it the "'to' form of the infinitive". Others simply call the verb part the infinitive and think of "to" as a "particle", in this case a word with the grammatical function of showing that the following verb is an infinitive.

For years as a child in school I was confused by the phrase, "the verb 'to be'", which I would hear spoken. I finally learned that they were merely referring to the verb "be" along with its many different forms including "is", "are", "was", etc. In like manner, the verb "to do" simply refers to the verb "do" and its other forms, "does", "did", etc.
